CHURN.

SPECIFICATION forming part of Letters Patent. No. 495,202, dated April11, 1893.

Application filed August 15, 1892.

To all whom it may concern:

Be it known that I, HENRY W. LANPHERE, a citizen of the United States,residing at Indian Lake, county of Hamilton, and State of New York, haveinvented certain new and useful Improvements in Churns, of which thefollowing is a specification.

My invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the letters ofreference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures.

Figure l of the drawings is a vertical central section of my improvedchurn, Fig. 2 is a similar view taken on the broken line 2 2 in Fig. l.Fig. 3 is a top plan view of Ythe skeleton step-plate the upwardlyprojecting arms being shown in cross-section.

A is the churn-barrel and Afthe churncover adapted to tit and close theopen end of the barrel.

The dasher-shafts, B-, B-, are each rotary in bearings in thechurn-cover and each shaft is provided with a plurality of dasherarms orbeaters, B-, preferably arranged upon their respective shafts spirallyand in such manner that the arms of one shaft alternate with those ofthe other shaft. Each is provided on its projecting end with a beveledgear, B2- adapted to mesh with, and be driven by, the beveled gear, C-,common to both, fixed upon the drive-shaft, C. The drive-shaft isprovided with a crank-handle, C2-, and is rotarily supported in bearingsin the brackets, 03- projecting from the supporting plate, C4 secured tothe cover, as by screws, O5. The plate, (34- also forms bearings for thedasher-shafts and their gears B2- and prevents the rotary parts fromwearing away the churn-cover.

The lower ends of the dasher-shafts are su pported in bearings BS- inthe step-plate, D-, which is secured to the churn-cover by means of theupwardly projecting arms, D. Such Serial No. 443,107. (No model.)

arms are preferably integral with the stepplate and project through thecover, the projecting ends being screw-threaded and provided with nuts,D2-, whereby such arms are secured to the churn-cover. Washers, D3-, maybe interposed between the nuts, D2-, and the churn-cover. The step-plateis thus adjustably connected with the churn-cover and any lost motiondue to Wear of the parts one upon another may be compensated by means ofthe nuts, D2. The cover may be secured in place by means of thespringclamps or hooks, A2.

By my improved construction, the entire beating mechanism is supportedby the churncover and maybe Withdrawn from the churn by lifting thecover, thereby affording easv access to the dashers forthe purpose ofcleansing the same. To cleanse the dashers, they may be supported in abarrel or tub containing water and given a few rotations by means of thecrank-handle, thereby quickly and thoroughly rinsing the submergedparts.

By having the beating mechanism and its bearings wholly supported by thecover, I avoid the necessity of attaching brackets or bearing-plates ofany kind to the interior of the churn-barrel; and when the cover and itsconnections are removed, the interior of the churn is left entirely freefrom projections of any sort adapted to secrete particles of butter orcream which would taint the churn. The step-plate is preferably made inthe skeleton form shown in Fig. 3, with the laterally projecting arms,D4-, adapted to approximately fit the interior of the churn-barrel. Sucharms bear against the inner wall of the barrel and prevent lateralvibration ofy the step-plate and dasher-shafts.

When desired the lower portion of the inner wall of the churn-barrel maybe beveled or contracted, as shown at AS- to enable the skeleton-plateto lit the bottom of the barrel while it is adapted to be easilyinserted in and removed from the upper portion of the barrel.

What I claim as new, and desire to secure by Letters Patent, is-

, In a churn,the combination with the churncover; of a pair ofdasher-shafts and a drive- IOO shaft severally supportedby the cover;gear In testimony whereof I have hereunto set connections between thedrive-shaft and dashmy hand this 25th day of July, 1892. er-shafts; astep-plate having a bearing-support for each flasher-shaft; and aplurality of HENRY W' LANPHERE' 5 arms proj ectng upwardly from thestep-plate Witnesses:

and cach adjustably secured to the churn- WILLIAM ALDONS,

cover, substantially as described. I I-I. L. FISH.
